ASo glucose can be stored as starch
BSo energy can be trapped as ATP
CSo all energy leaves as heat
DSo oxygen is never needed
Answer & Solution
Correct answer: B. So energy can be trapped as ATP
Stepwise oxidation releases energy in portions just large enough to be trapped as ATP instead of lost as heat.
